Riddle 4

I shall a while busy,
my servant,
with rings confin'd,
sedulously obey,
my bed break,
with noise make known,
that me a neck-band
my lord has given.
Me oft sleep-weary
man or maid
went to greet ;
I them, cruel-hearted ones,
winter-cold answer.
The warm limb
the bound collar
sometimes escapes from ;
it is, however, grateful
to my servant,
a half wise man,
that me there
something torments,
and he to my words
effectually may
a saying say.
